Abstract

A multi-beam antenna feed network (10) employs more aperture ports ( I, II, III, IV, V) than beam ports (ports A, B, C, D) to achieve low sidelobe lossless operation, particularly for cellular communications. With five aperture ports, signal value outputs at the aperture ports represent orthogonal outputs having phase gradients effective to provide a four beam radiation pattern. A feed arrangement (12) for the network (10) includes directional couplers and phase shifters intercoupled between the beam ports and aperture ports to provide the desired orthogonal aperture excitation.
